Purpose
To present the technique to achieve successful dalk without perforations in cases of extreme keratoconus and its postoperative management
Setting
A DALK surgery in a patient with long-term keratoconus, rigid contact lens user who presented an average keratometry of 89.5 diopters at Carlos Andrade Marin Hospital (Quito Ecuador)
Methods
A 61-year-old patient with advanced keratoconus underwent deep anterior lamellar keratoplasty with the manual Melles technique. The patient presented a marked alteration of the cornea's posterior curvature, so this most delicate area was surrounded for avoid intraoperative perforation. In the first 24 hours post-operatively, the pacient presented a pseudochamber caused by a marked ectasia of Descemet layer, which is why air was injected into the anterior chamber and a correct adhesion of donor cornea to recipient bed was obtained
Results
the patient is currently in his seventh postoperative month without complications and is in the process of removing sutures. His visual acuity improved from LogMar +2.00 to LogMar +0.50.
Conclusions
The Melles manual technique for deep anterior lamellar keratoplasty allows us to approach cases with extreme keratometries, allowing us to avoid penetrating keratoplasty and its possible complications.
